Answer:
The answer is A
Step-by-step explanation:
Answer:
x =
, y = -1.71
Step-by-step explanation:
sub y = x+4 in the first equation to get:
12 x - 5 (x+4) = -20
Simplify:
12 x - 5 x + 20 = -20
Further simplify:
7 x = - 40
Divie both sides by 7 to get:
x =
--> x = -5.7
Sub x =
in the second equation to get:
y =
+ 4 = -1.71
Answer:
-2/5
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 18-8)/( -15-10)
= 10/-25
